ARISS 20th Anniversary logoFor immediate release:

An ARISS Slow Scan TV (SSTV) event is scheduled from the International Space Station (ISS). This will be a special SSTV event to celebrate the 20th anniversary of ARISS on board the International Space Station.

Twenty years ago, on November 13, 2000, the Expedition-1 crew turned on the ARISS Ericsson radio for the first time and completed several contacts with ARISS ground stations around the world to validate the radio communications system.

These inaugural contacts launched an incredible two-decade operations journey on the International Space Station (ISS), enabling ARISS to inspire, engage and educate our next generation of explorers and provide the Amateur Radio community a platform for lifelong learning and experimentation.

The ARISS SSTV event is scheduled to begin on December 24 at 16:40 UTC and continue through December 31 ending at 18:15 UTC.

Note: Dates are subject to change due to ISS operational adjustments.

Images will be downlinked at 145.8 MHz +/- 3 kHz for Doppler shift and the expected SSTV mode of operation is PD 120.

Radio enthusiasts participating in the event can post images they receive at the ARISS SSTV Gallery at .

After your image is posted at the gallery, you can acquire a special award by linking to and follow directions for submitting a digital copy of your received image.
